Thermal processes in the stack of perishable cargo transported in the heated isothermal car

Abstract

The article deals with the organization of heat exchange processes when using a new heating system for the cargo room of the isothermal car. Using the example of considering a stack formed from glass containers with fruit juices packed in cardboard boxes, the equivalent thermophysical characteristics of the cargo in the stack are formulated. Analytical methods are used to determine the main regularities of the regular thermal regime and the nature of thermo-gravitational flows in the cargo room of the car. The possibilities of improving the design of the heating system of the cargo room of isothermal rolling stock for the transportation of perishable cargo are considered. The possibilities of modernization of specialized equipment allowing optimization of the temperature regime in the cargo room of the car are presented.
